6. The tolerance is -+1 in the 3rd significant digit.

The figure shows three forces applied to a trunk that moves leftward by 2.57 m over a frictionless floor. The force magnitudes are F1 = 5.25 N, F2 = 8.67 N, and F3 = 2.58 N, and the indicated angle is 0 = 60 (a) During the displacement, what is the net work done on the trunk by the three applied forces, the gravitational force, and the normal force? (b) Is there a net transfer of energy to or from the trunk? (c) Does the kinetic energy of the trunk increase or decrease? (a) Number i Units (b) v (c)
